Outcome Measures

Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Time to the First On-Study SRE (Non-inferiority) [ Time Frame: Up to 40.5 months ]
    Time to the first on-study skeletal-related event (SRE) analyzed for non-inferiority. Kaplan-Meier estimates of the median and its dispersion are reported.


Secondary Outcome Measures :
  1. Time to the First On-Study SRE (Superiority) [ Time Frame: Up to 40.5 months ]
    Time to the first on-study skeletal-related event (SRE), analyzed for superiority of denosumab. Kaplan-Meier estimates of the median and its dispersion are reported.

  2. Time to the First-And-Subsequent On-Study SRE [ Time Frame: Up to 40.5 months ]

    Time to the first-and-subsequent on-study skeletal-related event (SRE), analyzed for superiority of denosumab using multiple event analysis, the event must occur at least 21 days after the previous SRE.

    This outcome measure utilizes multiple event times, was analyzed based on a proportional mean model, and is therefore more appropriately summarized by the cumulative mean number of events.
